Implementation and principles of object serialization in Python

The pickle module can implement algorithms for converting arbitrary Python objects into a series of bytes (i.e., serialized objects). These byte streams can be transferred or stored, and then reconstructed into a new object that has the same characteristics as the original object. Notice: The documentation for pickle clearly states that it provides no security […]

dotnet explores the principles of SemanticKernel’s planner

When using SemanticKernel, I was fascinated by SemanticKernel’s powerful plan capability. Through the plan function, AI can automatically schedule and assemble multiple modules to achieve complex functions. I am particularly curious about the principles of the planner in SemanticKernel and how the underlying implementation is implemented. Fortunately, SemanticKernel is completely open source. By reading the […]
